Original application filed July 17, 1911, Serial'lifo. 638,994. Divided and this application filed April 22,

l 1912. Serial No. 692,400.

To all whom it may concern: i

Be it known that I, LUTHER J. IsENHopn,

a citizen of'the United States, residing at Indianapolis,in the county of Marion and I State of Indiana, have invented a new and useful Incubator and Brooder, of which the following is a specification, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon.

This invention relates to the type of incubator orbrooder that is adapted to be transferred from place to place in order to be hygienic, the invention having reference more particularly to the heating apparatus and to the heat controlling appliance thereof, more especially the improvements described in my pending application for Letters Patent of the United States filed July 17, 1911, Serial No. 638,994, of which this is a divisional application for Letters Patent.

The object of theinvention is toflprovide simple and reliable heating and heat-controlling apparatus for incubators, brooders or hovers, that shall be so constructed as to not be liable to derangement while being shipped from the factory or when roughly handled by the user.

A further object of the invention is to provide advantageous, cheaply constructed and durable and economical apparatus of the above mentioned character. f

The objects of the invention are attained in the structure illustrated in the accompanying drawings and hereinafter particu- Referring to the drawings, Figure 1 is" a front elevation of an incubator and brooder having the invention applied thereto; Fig. 2, a perspective view of a part of the heat regulator inverted; Fig. 3, a horizontal section approximately on the line A A in Fig. 1; Fig. 4 a fragmentary sectional perspective view of an improved heat radiator; Fig. 5, a fragmentary sectional elevation of parts of the heat regulator; Fig. 6, a vertical section on the line B B in Fig. 3; Fig. 7, a fragmentary section reproducing portions of Fig. 6 on an enlarged scale; Fig. 8, a fragmentary inverted planof the heat regulating apparatus; Fig. 9, a fragmentary perspective view of internal parts of the apparatus,

andFig. 10, a fragmentary sectional elevation approximately on theline C C in Fig. 8.

sulating material. shield 13 is secured to the under side of the floor 5 and extends downward a suitable like elements or features ofconstruction are indicatedv by corresponding reference characters.

The incubator or brooder includes a hous 1 ing or inclosure comprising a cylindrical metalllc wall 1 that is provlded on its inner side with an annular ledge 2 arranged some- .what above the normally lower end of the wall, thewall being provided with a lining 3 at theinner sidethereof that extends from the ledge down to the lower-end of the wall,

the lining preferably being removable and composed of suitable material that is a nonconductor of heat. The lower portion of the wall is provided with a suitably curtained door-way 4:. An apertured or open work elevated floor 5 is secured upon ledge 2, a

centrally arrangedguide-ring 6 being secured upon the-floor and extending about an opening in the floor, and a trap-door 7 is removably seated in the guide-ring 6. The guide-ring 6 is provided on its outer side with a socket 8 in which a supporting stem 9 is rotatively mounted and supports a thermometer 10 in inclined position both longitudinally and transversely, in order that the thermometer may be readily adjusted so as to be clearly visible in the best light afforded through the cover of the hous ing. An annular inner wall 11, composed of sheet-metal, is secured uponthe floor 5 concentrically with the wall 1 and it has an inner lining 12 composed of suitable heat-in- Preferably an annular distance immediately under the wall 11. The wall 1 is provided with a lining 1 1 that extends from the floor 5 upward to the upper end ofthe wall and may be composed of any suitable material that is a non-conductor of heat. i y y A heat radiator comprises a hollow annular water chamber formed of an outer wall 15, an inner wall 16, a narrow bottom 17 and a narrow top 18, the side walls being spaced a relatively short distance apart, and

the outer wall of the radiator is placed against the inner side of thelining 14 so as to prevent outward radiation of heat.

The radiator is connected with the wall lby means of asupporting pin 19 and is otherwise supported, as will become apparent.

Aradiatmg tube 20 is connected with dia metrically opposite portionsof the radiator and extends above the top of the wall 11,

I arranged that it is not obscured by the tube one end of the tube being secured to the wall 16 so thatv it is in-communication with the interior of the radiator, the opposlte end portion of the tube extending through both walls of the radiator and is secured thereto, the tube constituting a feed duct. A return duct 21 is arranged under the outer portion of thetube and is secured to the wall 15 of the radiator so that communication --isaifo-rded with the lower portion of the interior of the radiator. A brace 22 is preferablysecured to the wallil and the duct 21.

The tube 20 and'duct 21 extend through the 20. The" cover has a suitable lining stand normally rests removably uponthe wall 1 and the heat radiatorl The'cover preferably.

is provided withmet'allic clips 32 which'secure both the lining and the glass'plate or Window to the cover part 28', the latter having a flange 38 thereonthat extends down over the upper portion of the walll.

' A metallic bracket 34 is secured to the inner lower portion of the wall 1 where the latter is not materially a'ifected by changes of temperature, and it has'a' pillar35 formed integrally "thereon and extending upward through the floor 5, the upper portion of the pillar having'a plug 3'6 secured therein. suitable thermostatic device is provided for automatically regulating the heat in the housing and it preferably comprises a corso wall 1 h s a s 4 here n to rec ive he rugated disk 37 provided with a supporting, stem'38 which is screwed into the plug 36., a

disk 39, secured to the disk 37 and tWo simillajr disks 40 and 41secured togethenthedisk v 40 being secured to. the disk 30. and the uppermost disk 41 having a central bearing projection 42-thereon. A tubular journal bearing 43 extendsthrough and is secured to the Walls 1 1 16 o t ad ates the. 1' urnal-b a in x endi through t e W er space of the radiator and also through the walls 1 and 11 and their linings, and it sup ports a rock shaft 44 which extends therethrough and has a crank arm 45 on itsinner d P o w a c an handl Q pin 46..

An arm head is provided whereby to regulate the valve 30, and it, preferably comprises two side Plat d 49, securedto' the outer."

end of the shaft 44, and an integral top 50, and preferably also a bottom portion 51 at one end thereof. An arm 52 is arranged between the side plates 49 and 49" and extends above the shaft 44 and the bottom portion 51 toward the opposite end portions of the side plates, and it has a crook 53 thereon from which extends a return portion 54provi ded with a collar 55 which rotatably embraces the shaft 44 beneath the main portion. of the arm 52, said armextending to the operating. stem 31 and having aneye 56 thereon connected to'a similar eye with which the stem is provided. "Am-adjusting screw 57. is inserted in" the top 50 of the arm head and is in contact with the arm 52-for adjusting'the arm relative to the arm head, another ad} j'ust-ing screw 58 preferably beinginserted in the bottom portion 51and extending {into contact with the opposite side of the arm for assisting to hold the arm firmly adjllsted position, and it will be; understood that in some cases either one of the adjusting screws may be omitted. The arm headextends rearward trom the'valve gQ-beyond the shaft 44 $0 t0 partially counterbalanhe the a v 'ai d' t op a n ar 2- y In pract cal use the cover 1s removed from he housme" d eggs r plac's p n he fljc r 5; af er w i h h Cover is eplac d- Th he ting a p e n p in ope a io may be regulatedat will so as toheat the water which previously has been put into the he ter an th adi fhe atte dan may oo hrough e g a s P. te Q' n o sel e he m r in order tq scer-t n he temperature near the eggs, and if desirable either the lamp burner may; be readjusted, or
